Among women 18-29 less than 30 percent say their career or education has been hurt by sexism or child-care needs. The figures move higher with age. This is one of the reasons that Hillary Clinton draws more votes from older women than younger women. This is one of the insights from analysis of polling questions in a University of Massachusetts poll before the Massachusetts primary in Feb. 2016. Another insight from this article in the WP is that it also shows younger women think deeply about the issues. In a general election with Trump as the nomnee these women supporting Sanders are likely to vote for Clinton because of being alienated by the sexist comments of Trump. It helps that younger women are thinking deeply about the issues when so much is at stake in this election.
